What is the most venomous animal?

First, we should address the difference between venomous and poisonous. Most poisonous animals have toxins on or in their skin. They may secrete toxins that would be deadly to the touch – for either humans or other animals. So for poisonous animals, many scientists agree that the poison dart frog and some salamanders are the most poisonous. As little as two micrograms of toxin from the poison dart frog could kill a human.

A venomous animal also has toxins, but is typically delivered by biting, stinging or stabbing. While this is sometimes debated, the box jellyfish is often considered the world’s most venomous animal. You may have heard of the inland taipan of Australia as being very venomous, and it is. It is considered the most venomous land snake in the world.
